¥◇If the sponge gets dirty, the surface of the foundation will harden and it will be difficult for it to stick to your skin, so please keep it clean at all times. ◇When the sponge becomes dirty, use the separately sold "Shiseido Sponge Cleaner N" or wash it by lightly pressing it with a neutral detergent diluted with lukewarm water. After rinsing thoroughly so that no detergent remains, drain the water and dry well in the shade before using. If the comfort and finish are poor, please use the separately sold "MAQuillAGE Sponge Puff (SF)".
